Detailed Description

Container class provding information about the Hall structure of the problem variables.

This class is used to keep the number of different arrays small, that is an array of type HallInfo replaces integer arrays for each of the class members.

Member Data Documentation

Represents the union of all lower and upper domain bounds.

Definition at line 463 of file bnd-sup.hpp.

Critical capacity pointer t represents a predecessor function where $ t_i $ denotes the predecessor of i in bounds.

Definition at line 469 of file bnd-sup.hpp.

Difference between critical capacities.

d_i is the difference between the capacities of hall[i].bounds and its predecessor in bounds hall[t[i]].bounds

Definition at line 477 of file bnd-sup.hpp.

Hall set pointer.

If hall[i].h < i then the half-open interval [hall[h[i]].bounds,hall[i].bounds) is containd in a Hall set. Otherwise holds a pointer to the Hall intervall it belongs to.

Definition at line 486 of file bnd-sup.hpp.

Stable Set pointer.

Definition at line 488 of file bnd-sup.hpp.

Potentially Stable Set pointer.

Definition at line 490 of file bnd-sup.hpp.

Bound update.

newBound contains either a narrowed domain bound or is stores the old domain bound of a variable.

Definition at line 497 of file bnd-sup.hpp.
